Which I calculate is 28.00 hours

Most of the week was taken up with investigating three related areas:

*) How code such as -e 'BEGIN {1}' is compiled, and the interaction between
   PL_main_cv, CvSTART(PL_main_cv), PL_main_root and PL_main_start
*) Code in op.c which calls CopLINE_set(PL_curcop, oldline) and warnings from
   multi-line constructions
*) Building with -DPERL_DEBUG_READONLY_OPS to force shared ops to be
   read-only, and determining the causes of code trying to write to read-only
   ops

all of which aren't quite finished yet (even 1.5 days into "next" week), so
will have to wait until the next report for a (hopefully more) coherent
narrative.

The next report likely will be late as I'm at YAPC::Europe for most of next
week.
